[Description VPN-User 2007-04-01 19:00:24 UTC]

Hello,

I experience intermittent connection drops/errors on my ASUS M2N-MX onboard NIC using forcedeth driver with gentoo-sources-2.6.19-r5 (Stable x86).

Please try w/ latest vanilla-sources (2.6.20.3) and report back.

[Comment 3 VPN-User 2007-04-01 21:26:01 UTC]

When trying ~x86 vanilla-sources-2.6.20.3, module-rebuild has problems remerging alsa-driver.

[Comment 4 Jakub Moc (RETIRED) 2007-04-01 21:38:07 UTC]

Not much relevant whether module-rebuild has a problem w/ your ALSA, just test the forcedeth driver.

[Comment 5 VPN-User 2007-04-02 00:14:39 UTC]

Tried it. Problem still there.

[Comment 6 Farid 2007-04-03 09:21:45 UTC]

I have an Asus K8N mainboard. I've used the forcedeth driver with all kernel versions the last year. No problems here.
2.6.20-gentoo-r4 is what I use now. I am on amd64 though.

I think my hardware is alot newer. Here is what lspci says:

VPN-User: can you reproduce this on the latest development kernel, currently 2.6.21-rc6?

[Comment 10 VPN-User 2007-04-07 17:13:35 UTC]

How can I get it? I can' t find an ebuild for this one...

[Comment 11 VPN-User 2007-04-11 12:22:57 UTC]

I tried git-sources-2.6.21_rc3-r6 (which provides forcedeth v0.60) - Still same problem.

Within Windows OS using nVidia original driver, there is no problem.

[Comment 12 VPN-User 2007-04-19 13:31:07 UTC]

Bug still there in gentoo-sources-2.6.20-r6 (stable x86)

[Comment 13 Daniel Drake (RETIRED) 2007-04-19 13:58:22 UTC]

Are there any previous known working kernels?

Please test the latest development kernel, currently 2.6.21-rc7. See http://www.reactivated.net/weblog/archives/2007/04/using-ketchup-to-quickly-install-kernel-sources for one way to get this version.

[Comment 14 VPN-User 2007-04-20 13:29:52 UTC]

LOL! I solved it by ENABLING CONFIG_PCI_MSI=y in kernel config.

Whyever, it now works. Still a bug, or not? Because no MSI Interrupt is used:

Sorry. I thought I solved it. Still disconnections. But a lot more rarely when not traffic is flowing. When traffic is flowing, it still drops about every few seconds:

[Comment 16 Daniel Drake (RETIRED) 2007-04-25 15:45:20 UTC]

Are those results from 2.6.21-rc7?

[Comment 17 VPN-User 2007-04-25 18:22:00 UTC]

Yes currently it doent matter which kernel is used, it happens with every kernel.

I filed a bug on kernel.org, an nVidia employee has already accepted the bug.
